Inspections
Divetech Offshore performs a slew of subsea works. For a start, we carry out inspections or general surveys to ascertain the conditions of the target subsea structure and to ascertain if defects are present.
Our personnel include civil engineers specialised in marine operations, marine crew, plant operators, certified dive teams and inspection personnel that work on a myraid of subsea oil and gas structures that include Jack-up rigs, Semi-submersibles, Drillships and Floating Production Storage and Offloading (FPSO) structures.
Non Destructive Testing
When a closer visual inspection is required or when existing visual inspections yield suspected indications or defects on a subsea structures, a more detailed method of inspection will have to be performed. Non Destructive Testing (NDT) which comprise an array of inspection techniques will be the next step undertaken to enable clients to evaluate and collect data of the structure / material / dimensions without permanently altering it.
Common NDT techniques that Divetech Offshore performs subsea include Ultrasonic Testing (UT), Magnetic Particle Inspection (MPI), Eddy Current Testing, Alternating Field Current Measurement (ACFM), Flooded Member Detector (FMD) and Cathodic Protection (CP) readings on anodes.
Repair & Maintenance
Offshore structures are designed and built to withstand the harshest of conditions miles away from shore. These structures however will deteriorate due to wear and tear, material failure or other reasons. To address this, a comprehensive Inspection, Repair & Maintenance (IRM) programme will target and identify items that requires renewal or replacement.
Divetech Offshore has an extensive track record in performing subsea IRM works and these works range from basic tasks of marine growth removal to to more complex works such as anode replacements, reinforcement clamps and components replacements.
